Drop connections to port 80 at firewall machine also drop at protected network?

Dear friends,

If I do not accept connections to port 80 of my firewall machine, does it mean all connections to port 80 within the protected network will not work also?

I was troubleshooting my proxy this morning, I allowed port 80 http connections to the protected network but the internet connection didn't go through. After I inserted a script to allow port 80 http connection to the firewall machine itself, the internet started to work.

Maybe you need to describe your network better, but it seems you want to drop connections from your external interface (ie: the one attached to the internet) and accept them from your internal interface (the one attached to your protected network)

Yeah, thats what i am trying to do. On the firewall machine itself i don't want it to be able to browse but I want the LAN computers that it protects to be able to browse internet.....

I am really confused about INPUT Chain and forward chain...I used to think that anything to do with the firewall machine itself are controlled at the INPUT chain, anything to do with the machines it protects are related to FORWARD chain. But seems like that idea is wrong.
